Abstract

The embodiment of the invention provides a navigation trajectory prediction method, a computer storage medium and a program product. The navigation trajectory prediction method comprises the steps that port position data and historical ship route data are acquired, and the historical ship route data comprise historical navigation trajectory points of a ship; according to the port position data, historical navigation track points matched with the port position are determined from the historical ship route data; the historical navigation track point matched with the port position is used as an end point, the historical ship route data are segmented, and historical route data marked with a historical departure port and a historical destination port are obtained, so as to determine a historical departure port the same as the current navigation departure port of the target ship, and the navigation trajectory of the target ship is predicted according to the historical route data corresponding to the historical departure port.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular to a navigation trajectory prediction method, a computer storage medium, and a program product. Background technique [0002] With the continuous development of shipping, ocean transportation has become one of the important ways to exchange commodities internationally, and the total amount of freight transported by ocean is still increasing. However, the sea traffic lines are extremely complicated. If traffic accidents occur frequently, it will cause huge economic losses and cause huge hidden dangers to the safety of people navigating at sea. In order to improve the safety of ocean transportation, avoid ships entering dangerous waters or bumping into walls, and reduce the fuel consumption cost of ocean transportation, it is necessary to accurately predict the future navigation dynamics of ships. [0003] In general, when predicting the trajectory o...
